l Application filed January?, 18.84. Serial No. 116.678. (No modeLl .To all whom/zit 77mg/ concern:

Be it known thatI, CARL GTTINGER, a cilzen of the Republic of Switzerland, and a resident of Camden, New Jersey, United States of America, haveinvented certain Improvements in Embroidering Machines, ot which the following is a specification.

Myinvcntion relates to improvements in that class of embroidering-machines in which asus- IC pended frame carrying the stretched fabric to be embroidered is so combined with a seriesl ofembroideriug devices and pantograph mech anism and is so traversed that a series otl figures exactly like each other and like a given f5 pattern will he embroidered simultaneously on the said fabric.

My improvements,which are fully described hereinafter, are directed, mainly, to the embroidering mechanism, to pantograph mechanism, to a device for simultaneously cutting all the threads when such a proceeding is required, and to mechanism or notifying the attendant when one or more of the threads break.

fully understood, I have deemed it necessary to illustrate and explain the machine in l'ull, including many features which are to be found iu other machines, such as that Vdescribed in 3o .Patent No. 262,383, granted to J. Ebneter,

` August 8, 1882, and the Patent No. 271,182, granted lo the assignees of O. N. \Vurth,gJan uaryB, 1883.

` In order to avoid repeated interruptions in t-he description, I have not, in proceeding with the latter, distinguished what is old from what I consider to be new, as the features which constitute myimprovements are fully set forth in theclaims, by which this distinction can be 4oireadily made.

In the accompanying drawings, Figure 1, Sheet 1, is a front view of an embroideringmachine embodying my improvements without illustrating the detailed construction of the parts; Fig. 2, Sheet 2, avertical section on the line 1 2, Fig. 1; Fig. 3, Sheet 3, a vertical section ot' the needle mechanism of the embroidering devices; Fig. 4,A a sectional plan of Fig. 8; Fig. 5, a transverse section on the line In order that my improvements may be 3 4, Fig. 8; Fig. 6, a detached perspective 5o View of part ofthe needle mechanism; Fig. 7, f Sheet 4, avertieal section of the looping mechanism; Fig. 8, a sectional plan of the same; Fig. 9, a transverse section on `the line 5 6, Fig. 7, showing the spool in elevation; Fig. 10, a transverse section on the line 7 8, Fig.

To prevent confusion, the description has been separated into sections under the following heads, namely: First,aw general description of the frame-work of the machine; second, the embroidering devices; third, gearing for driving the needle and looping mechanism; fourth, the pantograph mechanism; `tth, cooperation ot' the pantograpli mechanism with -the embroidering mechanism; sixth, the cutting-off mechanism; seventh, mechanism for retaining the threads while they are being cut;

, eighth, signaling to indicate the breaking of 'frame-work will be referred to hereinafter.

It should be understood that in carrying out my invention it is not essential to adhere to this frame-Work, which l, however, prefer, as it is well adapted to the purpose, and is as light as it can be made consistent with proper stability. The frame D', Fig. l, upon which the fabric to be embroidered is stretched, and which is therefore termed the embroideringframe,77 consists of two longitudinal trussed bars, d d', connected together at each end by the vertical bars e e', the whole being preferably cast in one piece. The oblong space bounded by the bars d d and e e' is open, and across this space is stretched the fabric to be `embroidered, but at one end of the frame -is secured the pantogra'ph-plate E, and at the opposite end ofthe frame the pantograph-plate E', these plates being specially referred to here inafter in another branch vof the specification. The embroidering-frame is counterbalancedby weights F F-one near each end ofthe framework ofthe machi ne-the chain c, to which each weight is suspended, being secured to and partially surrounding a pulley, F', in one groove of the same,andanother chain,attached to the same pulley and partially surrounding 'the same, being attached to a pulley-carrier, b, o n the pulley b', in which is a groove adapted to a bar, e, ofthe einbroidering-frame, in which is an elongated opening, j, this arrangement being the same at both ends ofthe frame. The two pulleys F' F' are secured to a shaft, f5, one near each end of the said shaft, which has its bearings in the end standards, A A', of the frame-work of t-he machine. Each of the pulley-carriers b is guided laterally by the vertical bars h h', which are secured to the frame-work of the machine, projections g g' of the carrier bearing lightly one against one bar and the otheragainst the opposite bar, as shown in Fig. 2, the guit'ling-bars being omitted in Fig. l to prevent confusion. It will be seen that the embroidering-irame thus balanced and suspended can be traversed in all directions,longitudinally, vertically, and diagonally, but always in the same plane. Before leaving this part of the description I may refer to the positions indicated by the letter in Fig. l of the several embroidering-machimes-twelve in the present instance. I mayalsgo ,point to the position of the pattern-board Gon one end of the embroidcriiig-frame, and

to that of the driving-shaft H, which has its bearings on the extension D of the framework.

The embroidering devices. -T11cse are illustratcdin detail ou Sheets 3 and 4, each embroidering device, and they are all alike, con.- sisting of two main parts-namely, the needle mechanism shown on Sheet 3, and thc looping mechanism illustrated on Sheet 4- the twelve looping mechanisms being on the bed of the fixed frame ou one side of the embroidei'ingli'amc, and the twelve needle mechanisms on the bed C' on the opposite side of the said emhroidering-frame, as shown in Fig. 2.

Referring, in the first instance, to the needle mechanism, I is a small frame secured to the above-mentioned bed C' of the frame-work at and fi, Fig. 3,`and J, K, and L are three longitudinal shafts common to all the needle mechanisms, the shaft J being rotated when the machine is in operation, the rock-shaft K being vibrated while the shaft L is under the control of the attendant. y An arm, K', on the rockshaft K is connected by a rod,j, to a sleeve, j', which is so connected to the tubular rod j that while the latter can turn in the sleeve it must be reciprocated therewith, the needlebar k being contained within the tubular rod and terminating in the needle It", which is guided by a nipple, k2, at the outer end of the Vtube L', which is arranged to reciprocate in the tubular shaft U, vthe latter having its bearings l Z on the small frame I. A cog-wheel, m, on the tubular shaft L2 gears into a similar wheel, m', on a stud, m2, secured to the small frame I, and on the said wheel lm' is a bevelwheel, m, gearinginto a similar-wheel, my", Fig. 4, on the shaft L. Asmall block or key, n, is

adapted to elongated slots in the tube L', and

lthe tubular rodj'l has a threaded stem passing through a slot in thetubular shaft L2, so that all these parts must turn together, while the tube L' and tubular rod j2 can be reci procated independently of each other and of the tubular shaft L, tlie needle-bar being carried by and reciprocating with the said tubular rod f". A reciprocating movement is imparted to the tubeV L by an eccentric, a', on the shalt J,

through the medium of the eccentric-rod fn?,

and lever 91,3,pivoted to the frame I, the upper forked arm of this lever having pins projecting into an' annular groove at the rear end of the tube L'. A pin, a@ passes through an elongated slot inthe eccentric-rod nf", and thev lower endof the leverA u" is connected to the frame of the machine by a spring, fn", which tends to force thelong arm of the lever in the direction of its arrow. Owing to the pin n* passing through an elongated slot in the eccentric-rod of, the vibration of the lever a, and consequently the reciprocation of the tube L', is intermittent, for a purpose explained hereinafter. The eccentric a' is loose on the shaft J; but apin, '12', is adapted to an opening `iu said eccentric and to a recess 'in the counterbalancing eccentric p, so that so long as the pin is .in place the two eccentrics are locked together and rotate with the shaft J. Accidental displacement of thelocking-pin p is prevented by a spring, p", which is adapted to a notch inthe pin, as shown in Fig. 8; but when it is desired .to stop the rcciprocation of the tube L the spring can be raised and the pin withdrawn, thus freeing the eccentric a from the control of the fixed eccentriep. There is a ring, q, loose on the tubular shaft L, and secured to this ring is a key, q', arranged to fit both in a groovein the shaft and in a groove in the hub-of the wheel m. When the ring and key have been moved away from the Wheel, as shown in Fig. 6, there can be no vibration of the said tubular shaft; but when the ring has been adjusted against the hub of the wheel, the key being in the groove of both shaft and wheel, the former must vibrate. In order to keep the ring in contact with the hub of the wheel I interpose a segment, t, between a collar, t', on the tubular shaft and the ring q, the segment forming part of an arm, M, Fig. 5, which is pivoted to the frame of the machine, and which can be thrown back when it becomes necessary to throw the shaft out ofgear with the wheel.

The movements of the above-described parts may be briefly summarized as follows: First, the uniform reciprocating movement of the needle, by which the hooked end ot' the latter is caused to pass through the fabric on the embroidering-frame, at the rear of which it cooperates with the looper, described hereinafter, to seize the thread and draw a loop backthrough the fabric5`second, an intermittent reciprocating movement of the tube L and ils nipple k2, th rough. which the needle passes, the nipple, owing tolthis intermittent movement, being in contact with the fabric as the needle enters the same and as it is withdrawn therefrom, there being an interval, during which the nipple is clearof the fabric while the latter is being traversed by the frame. rlhese two movements are derived from the drivingshaft of the machine, third, the turning of the needle by operating the shaft L, which is under the control of the attendant, and which acts in unison with the pantograph appliances in a manner and for a purpose explained hereinafter.

1n connection with the tubular shaft L2 is a threadcutting device, part of which consists of the rod M', but which will form the subject of a special description.

rlurning now to Sheet 4, which illustrates the looping mechanism of the embroidering devices, it will be seen that a small frame, l', is secured at t" z" to the bed C ofthe machine, the said bed being composed ofthe longitudinal beams ca. (Shownin Fig. 2.) Two shafts, N N', common to all the looping devices of the machine, have bearings in the small frame l',

and to bearings Z l in the said frame l is D adapted a tubular shaft, L, and within this shaft is the looper-spindle N5, in which is cut sa a a screw-thread, preferably a double thread, adapted to a like internal thread in a sleeve, l?, which fits snugly and is arranged to slide freely in the tubular shaft L, which is connected to the eccentric-rod I, the strap of the latter embracing the eccentric F, loose on `the shaft N, and the connection being made inthe manner shown in Fig. 8, where it will be observed that pins on the forked end of the eccentric-rod project into a two-part ring confined between collars on the tubularshai't.

Secured to the shaft N is a counterbalanceeccentric, P, and the connection between the same and the eccentric P is similar to that before described in connection with the eccentrics n and p of the needle mechanism. A cogwheel, Q, on this shaft gears into a similar wheel, Q', on a stud, Q', secured to the small frame l', and on the latter is a bevel-wheel, b,

'gearing into alike wheel, b", on the shaft N.

Thereis a device precisely like that shown in Figs. 5 and 6, by which the wheel Q may be thrown into or out of gear with the tubular ysh aft L3. v

A spool, R, ot' thread is carried by a spindle, a', on a yoke, 1t', secured to a projection, ai, on the tubular shaft, the thread .from the spool passing first through an eye, n, referred to hereinafter, and thence through any one of a number of eyes on a plate, w, attached to` the end of the tubular shaft L", and thence through an eye, '10, in the looper S, which is attached to the end of the looper-spindle The eye w, above referred to, is on the outer end of a small rod, w', which can slide in a projection, y, on the tubular shalt L3. Alight arm, c, is pi voted to the yoke R', and is caused, by a light spring, o', also secured to the yoke, to bear against aprojecling pin, y', on the sliding rodw, so that the latter always has a tendencyto move'in the direction of the arrow, and to enter the nearest of a number ot' orifices, fr, in the upper portion of an arm. S', which is hung loosely to the tubular shaft L, but this tendency is couuteracted by the thread passingunder more or less tensirm in the direction pointed out. I t should be stated here that the shaft N is under the cont-rol of the attendant, and operates in unison with the pantograph mechanism explained hereinafter. lf a thread breaks during -the movement of the tubular shaft in itsbearings, the sliding' rod w will be released, and the spring n', acting on the rod through the medium ot' the arm e, will force the said rod in the direction of the arrow, and will enter one of the orifices ofthe arm S and move the same, causing it to strike any signaling device, which may notify the attendant of the accident and prompt him to arrest the machine. rl`his signaling device, depending for its action on the breaking of a thread, has been explained here, owing to itsintimate relation to the looping mechanism, but it will be referred to hereinafter in another branch of the specification in connection with signaling` devices. The sleeve'P is in section of the form shown in Fie. 10, or it may be of any TOO IIS

IZO

other shape which will prevent it from turning independently of the 'tubular shaft L, while it is at liberty to be reciprocated therein, in order to impart the desired vibrating motion to to the looper-spindle and looper.

Gear-my for driving the needle and looping 'inechaasnnhefore leaving the looping and needle mechanism it .will be well to refer briefly to the gearing through which the shafts of these mechanisms are driven. This can be best explained by reference to the plan view, Fig. 12, Sheet 5, in connection with the Vertical section, Sheet 2.

V In Fig. 12, D is the extension of the frame referred to in connection with Fig. 1, C being the bed to which the series of looping devices above described are secured, and C the bed which carries the series of needle mechanisms. The extension D of the frame carries the bearings s s', Fig. 12, for the counter-shaft Y, which is driven from the main shaft of the machine in a manner explained in a separate branch ofthe description. This shaft is geared by bevel-wheels .stand s to the longitudinal shaft N, which, as before remarked, is common to all the looper mechanisms, this being the shaft by which every looper-spindle is reciprocated, through the medium of devices illustrated on Sheet 4, and fully described above. The counter-shaft Y is geared to a longitudinal shaft, T, which is discontinued at x', Fig. 12, for the introduction of mechanism f do by which theysaid shaft is caused to actuate the two shafts J and K, which, as before remarked, are common to all the needle mechanisms, and which are shown in Sheet 3 in connection with one of the needle mechanisms. In Fig. 12 the. shat't K only is shown, the other shaft, J, being directly below it. In Figs. 13 and 14, however, is shown the relation of the shafts J and K to each other, and the wheels V V', by which the two shafts are geared together, for the shaft J of the needle mechanisms must rotate continuously while the machine is in operation, the shaft K, on the other hand, being vibrated, and this vibration is effected by mechanism illustrated in 14./ A crank-pin. on the wheel V is connected by a rod, x2, to a rocking arm, V2, pivoted to the frame ot' the machine, and this arm is connected by a rod, V3, to an arm, V, on the shaft K; hence itwill be seen that while the shaft J, appertaining to the needle mechanisms, rotates continuously the shaft K, appertaining to 'the same mechanisms, is vibrated.

APaatograph mechanisms. Referring in the first place, to Fig. l, it has been remarked that the embroidering-frame D' is provided with two pantograph-plates, E E', one at each end of the frame; there are consequently two pantograph mechanisms carried by the frame of the machine, and operating in unison with each other, and each pantograph mechauism'is composed of t'wo parts, (shown in their proper relation to each other in Fig. 15, Sheet 6,.) one part carrying one pantograph-wheel, f, the

other carrying the opposite pantograph-wheel,

f2, and one of the pantograph-plates, E, of the also arranged to be turned laterally simultane ously and in unison with each other, and with the two shafts V \V,which are in line with each other, one shaft appertainingto one part and the other shaft to the other` part of the pantograph mechanism. The movement of the embroidering-frame is due to the rotation of the two wheelsf/andfz, which act on'the pantograph-plate E, and the direction in which the embroidering-frame moves will depend upon the plane in which the wheels revolve, and the wheels can be adjusted to intermittently revolve in any desired plane by turning the shafts W W. v

As both parts of each embroidering mech anism are nearly alike, I will proceedv to describe that part illustrated in detail by Figs. 16, 17,` 18, and 19, Sheet 7. The shaft \V, above referred, to as carrying the pantographwheel f', is adapted to bearings if if, secured to one of the end standards of the main frame of the machine. A shaft, L, which has been referred to in connection with Figs. 3 and 4,v

Sheet 3, has its bearings in a stand, J', secured to the extension D of the main frame of the machine, and a bevel-wheel, Jf, on this shaft gears into a bevel-wheel, J, on a fixed stud, J, a cog-wheel, y, on the hub of the wheel J3, gearing into a cog-wheel, g2, on the shaft W, into the end of which is screwed a stud, \V`', having a rounded end, ci, against which bears the -rounded head cis of a pin, W, both heads being contained in aI two-part cylindrical block, Vv, which is arranged to slide in a sleeve, NV", secured to the bearing h2. A plug, Y', screws into the end of the fixed sleeve W, this plug having a worm-wheehYg, which will be referred to hereinafter. On screwing the plug into the end of the sleeve the sliding block W, and consequently the shaft XV, will be moved in thedirection of the arrow, (Fig. 17 and the pantograph-wheel j" will be forced against the pantograph-plate with a yieldingpressure, however, as a spiral spring, Ys, is interposed between the end of the plug Y and the sliding block V Thejournals di of the pantograph-wheelf have their bearingsin a carrier, X,`secured to the shaft XV, and on a hub of the said pantograph-wheel is a worinwheel, X', into which gears a worm, X, on a spindle, X, which has its bearings in the carrier X, and which has a cog-wheel, X4, gearing into asimilar wheel, X, on a shaft, X, which also has its bearingsin the carrier, and to which is secured a ratchet-wheel, c2, which is prevented .from turning, excepting in one direction, by a spring-catch, e, an arm, 6*, loose on the spindle X", having a spring-pawl, e", the point of which is adapted to the teeth ofthe ratchet-wheel ci. The arm el is connected by a rod, T, in the interior of the shaft .l OO

This shaft T is a power-driven shaft and the shaft L is controlled by hand, lthe location of these shafts on the machine being explained hereinafter. termittent motion to the pantograph-wheel f through the medium of the devices which have been too fully described toneed enumer-` ation, and bymoving the shaft L by hand the shalt NV, and with it the carrier X and pantographwheelf, will, be turned. i

Referring back to Fig: 15, Sheet G, it will be seen that the mechanism last described for operating the pantograph-wheelj, and illustrated on Sheet 7, occupies a position on the left of Fig. 15, the mechanism on the right of the iigure for operating the opposing pantograph-wheel j* being similar to that on the left, with this exception, that the arm g4 is vibratcd directly from the shaft N by a crankpin, S", and rod S.

lt will now be necessary to refer to Sheet 5 in order to describe the gearing by which the hand moved portions of the two parts of the pantograph devices are operated simultaneously and in unison. The dotted lines i'l and i, Fig. 12, indicate the centers of the shafts W W of the two pars of the pantograph mechanism shown in Fig. 15, one shalt carrying the pantograph-wheel j and the other shaft the pantograph-wheel f2, between which the metal A shalt, B", having its bearings in the extension l) of the frame, is provided with an opv- @rating-handle. B, and is geared by miterwheels f i and f to the shaft L, and by similar wheels, j and f, to the shaft N', these being the shafts by which the shafts XV W', Fig. 15,

f carrying the pantograph-wheels, are turned on their axes through the medium of the mech anisin described above. Two spindles, F2 and F", have their bearings in attachments to the frameof the machine, the spindle F2 being geared by miter-wheels Il and F5 to the shaft N and the spindle F, bysimilar miter-Wheels, F and Fl, to the shalt L, Fig. 12. Each of these spindles carries a wheel, D, one wheel on one side and the other on the opposite side of the pattern-board G of the embroidering` frame, the sole object of these wheels being to steady the frame. The shafts,however,which carry the wheels operate in unison with the shafts V XV', carrying the pantograpl1-wheels, so that the latter shall always revolve in a A two- The rotating shaft Twill impart an inplane parallel with that in which the said wheels D* turn. The spindle F3' is geared to the pointer-spindle z, as shown in Fig. 20,and it is to the point of this spindle and to the pattern on the board G that the operator directs his attention in manipulating the handle B3, by which the repetition of the pattern on the fabric on the embroidering-'frame by the different embroidering mechanisms is assured.

The pantograph mechanism which operates in connection with the pantograph-plate E at the outer end of the embroidering-irame is precisely similar to that above described, excepting that there is no pattern-board G and no pointer at the opposite end of the said frame, the action of the pantograph-wheels, in connection with the plate E', simultaneously and in unison with that of the pantographwheels f f @in connection with the pantographplate E, being assured by extending theshafts N and L and gearing them to the pantograph mechanism, operating in connection with the said plate E', precisely in the manner described above.

C0 operation of the panter/mph mechanism with the embroitlert'ng mcchtmism.Reierring to Fig. 21, which shows the looper S on the end of the louper-spindle N and the hooked necdle, it is essential that the needle should turn in unison with the pantograph devices which feed the embroidcringframe, so that the hook of the needle may not present itself in direct opposition to the direction in which the fabric is fed, and it is also essential that the looper shall turn in unison with the needle. This turning of the looper and needle is-etfected by ICO the shaft B2, from which also are operated the pantograph devices, the shafts `N and L being, as before seen, geared to this. shaft, and the said shafts N and L being common to all the embroidering mechanisms, and the mechanism through Which the looper and needle are turned from these shafts in unison with the pantograph devices has been explained in referring to the views on Sheets 3 and 4.

The action ofthe pantograph devices on the embroidering-frame is intermittent, and there is no movement of the frame while the needle is entering or being withdrawn from the fabric, the movement of the iframe being effected while the needle is clear of the fabric.

The intermittent action of the pantogra-ph mechanism in unison with the emlinoidering devices is brought about by the proper timing of the devices by which the pantograph-wheel is intermittently rotated `and the devi ccs which operate the needles. As above remarked, the pantograph-wheel f is caused to bear against the pantograplrplate E of the frame by manipulating the wheel Y2, Sheet 7 but as there are two pantograph devices-one at each end of the einbroidering-irame-it is essential that both should be simultaneously brought to bear against their respective plates, and when necessary simultaneously retracted from the said plates, so as to release the same from the control of the pantograpli-wheels. This TIO simultaneous action ol' the two pantographwheels is brought about by a shaft, Z', Figs. 1 andl', which is geared at one end by a wheel, z2, to the wheel Y2 of one pantograph device, and by a similar wheel to the wheel Y2 of the other pantograph device, the shaft Z', which has its bearings in brackets secured to the main frame of the machine, being provided with a suitable handle, z2, Fig. 1, within easy reach of the operator of the pantograph device.

' Getting-off devce.-This'device isillustrated in Fig. 3, Sheet 3, Fig. 21, Sheet 5, Figs. 22 and 23, Sheet 8, the operatingdlandle only being shown in Figs. l and 23. Referring to Fig. 3, it will be seen that a rod, M', previously referred to, is secured to the tubulaishaft L2 of the needle mechanism. To the outer end of this rod is secured a concave-convex shield, M2, through an orifice in the center of which passes the nipple k2 on the tube L', and through the nipple passes the needle, the thread seized bythe needle being drawn through the orifice of the shield when the nipple is retracted. The pin Miof a lever, Mi, is pivoted to the rod M', one arm of this lever consisting of a knife, g2, Fig. 22, adapted to the concave inner side of the shield, and the other arm being connectedby a rod, q, to a collar gf, which is arranged to slide on the rod M', a spring, Z2, tending to keep the knife q2 away from the orifice in the shield and from the course of the thread. After the nipple and needle have been retracted the thread maybe instantly severed by sliding the collar g* forward toward the shield ,the knife, after performing th is duty,

being restored by the spring Z2 to its former position on releasing the collar q,

In order that the threads of all the embroidering mechanisms may be simultaneously severed,ashaft,U, (shown inthe perspective view, Fig.23,}extends along the frame of thcmachine, and this shaft has as many arms U' as there are embroidering devices, each v arm being arranged to bear against the collar qof each rod M. A A shaft, U2, having its bearings in the frame of the machine and provided with a handle, U2, the location of which is shown in Fig. l, has an arm, r, connected by a rod, r', to an arm, r2, Fig. 23, so that by manipulating the handle all the threads of all the embroidering devices may be simultaneously severed. It should be understood, however, that this is done after the machine has been stopped and the needle retracted, the severing being requiredei ther after a series of embroidered patterns have been completed or when it is necessary to discontinue the embroidering atany specific part of the pattern and to recommence lthe same at a distant part of the said pattern.

llleclzansm for retaining the lhreatls while being cut.-It is advisable that the th reads should be held so as to be underslight tension while they are being cut. The thread-holding device is shown in part in Fig. 7, Sheet 4, and in full in Figs. 24, 25, and 26, Sheet 9. Referring to isms.

Fig. 7,' it will be seen that there is in front-of the looper a bar, E2, through which the rod passes. This bar extends nearly throughout the entire length ofthe frame of the machine, andis shown in Fig. 24, where are also shown the longitudinal beams C C' ofthe frame, the

.dotted line in that figure representing the 'and to which is secured an arm, El, extending upward and between projections on the bar E2.

On releasing the-weighted lever E the sliding bar E will move back to its former position. I prefer for raising the weighted lever Ff a rod, C2, attached at its lower cud to the bar and at its upper end to an arm, C', attached to a small shaft, C2, having its bearings in the uppei` portion of the frame, and provided with an arm, C, from which is suspended a rod or cord, Gl, terminating in a suitable handle within reach of the attendant.

Turning to Figs. 25 and 26, which 'arc enlarged views of the bars E2 E3 and their attachments, a small bellcrank-lever, l2, is pivoted by a pin, I2, to the bar El within a recess in the same, one arm of the lever passing through a notch, I4, in the bar E, and the bent end of the other arm being above the orifice through which the thread passes. Vhen the bar Ff* is moved in the direction of the arrow, Fig. 25, by the appliances described above, the bent arm of the lever will be depressed, and will hold the thread against the bar E2, as shown in Fig. 26, until the weighted lever E2 is released, when the lever l2 will be restored to its former position and the thread will be at liberty. There is one of these holdinglevers for each of the embroideringmechanisms, so that when all the threads have to be severed the attendant must pull the rod C7 with one hand, thereby holding all the threads, and then manipulate the handle U, thereby severing all the threads. f

Signaling device for indicating the breaking of one or more threads-It has been stated, in referring to Figs. 7, S, and 9, Sheet et, that if a thread breaks during the movement of the tubular shaftin its bearings, the sliding lrod fw will be released and the s rinfr'tk acting on the rod through the medium of the arm n, will force the said rod in the direction of the arrow, and will enterone of the orifices of the' arm S' and move the same, causing it to strike any signaling device which may notify the attendant.77 Fig. 27 shows the signaling device which I prefer to use. A rod, A2, extends nearly throughout the entire length of the frame, and is arranged to slide in guides on one of the longitudinal beams. This rod has a series of pins, Ai, one for each of the embroidery mechanisms, each pin being so situated as to bestruck by one of the arms S, above referred to. An arm, A", on a shaft, A, adapted to bearings A, secured to the floor, extends between two projections, H, on the n sliding bar A2, and an arm, H2, on t-he same sys shaft, is connected to a bar, H3, which is carried by brackets Ht, secured tothe frame of the machine, and is arranged to slide freely on guides on the said brackets, this bar H3 having a projection, H5, which, when moved in the direction of the arrow, will release an elasi tie arm, H, carrying a bclland pivoted to an attachment on the arm At, so that there will be a ringing of the bell whenever the rod 'is moved in the direction of its arrow, and this will be the case whenever any one or more of the threads break.

In order to enable others to construct and operate the machine, it has been deemed best to introduce complete illustrations and descriptions ofthe starting and stopping mechanism. This mechanism is illustrated in part in Fig. 1, Sheet 1, and more fully by Figs. 2S, 29, and 30, Sheet 8, and by the skeleton perspective view, Fig. 3l, Sheet 10.

Referring to Fig. 28, it will be secu that the driving-shaft His furnished with a fast pulley, 2, and a loose pulley, 3, in connection with which is a belt-shifting bar, 4, adapted to guides on the extension D of the frame-work of the machine. A driving-rope, Nt, passes round a driving-pulley, N3, and round a pul-l ley, N4, on the counter-shaft Y, from which the several embroidering mechanisms derive their movements through the medium of the gearing described above. The pulley N3 is composed of two parts, 5 and (i, the former movable and the latter fixed to the shaft H, each part having inclined arms, which pass through the spaces between the inclined arms of the other part. By moving the part away from the part 6 the effective diameter of the pulley will be decreased,and the nearer the part 5 is adjusted t-o the part 6 the greater will be the effective diameter. The pulley N4 on the counter-shaft Y is precisely similar, the part 7 of this pulley being adjustable and the part 8 fixed on the shaft. Hereinafter l shall designate these pulleys as expansible77 and contractiblc pulleys. A lever, D?, pivoted to a stud, 12, on the frame 'of the machine, has three arms, 9, 10, and 1l, the latter being connected to a collar on the hub of the loose portion 5 ofthe pulley F, and thc arm 10 ofthe lever by a rod, 13, to the short arm 14 of a lever, D, which is also pivoted to the frame, and the long arm 15 ofwhich is Iconnected to a collar on the hub of the movable portion 7 of the pulley N* on the counter-shaft Y. The arm 9 of the lever D2 has a toothed segment, 16, into which gears the pinion 17 on the shaft 18, which has its bearings in the frame of the machine, and which is geared by bevel-wheels 19 and 20, Fig. 29, to a shaft, 21., which has its bearing in a bracket, 22, secured to the frame. To the end of the shaft 2l is pivoted a hand-lever, 23, which can fit into a notch, 24, in the circular flange 25, forming part of thebrackct 22, on the edge of which flange there is also a projection, 26. (Shown in 30.) lt will bc necessary here to refer toFig. 12, noting, in the first instance, a flanged disk, 27, secured to the shaft N, the stoppage ol' which must result in the stoppage of the entire power-driven operating parts ofthe machine. It is important that when the machine is stopped all these parts should' be in a `given position, all the needles being retract-ed. The llanged disk 27 has a recess Vinclined on one side and abrupt on the other, and when the motion of the machine has to be arrested a stop, 2S, enters the recess ofthe `flange, and the abrupt end of the recess comin in contact with it, there can bc no further rotation ofthe shaft; but this stop must operate in connection with the belt-shi fting device, and this it does through the medium of mechanism which can be best described in connection with Figs. 29 and 31. Vhen the hand-lever 23 is in the notch of the disk 25it is in contact with, but has not been forced hardagainst the' end of a short guided rod, 29, connected to an arm, 30, on a vertical shaft, 3l., which has its bearings in attachments to the frame ofthe machine, and on which is another arm connected by a rod, 32, to an arm, 33, on a shaft, 3ft, which also has its bearings in the frame-work of themachine, and which has an arm, 35, connected to the belt-shifting rodi. A vertical rod, 3S, possessing slight elasticity, is secured at its lower end to an attachment on the frame, and terminates at the top in a head, 39. The above-mentioned stop 2S bears on this head 39, not permanently, however, for the stop has a pin, 4-0, passing through the head 39, and a spiral spring coiled round the pin intervenes between a head on the pin and the under side of the head 39, so that when the abrupt termination of the notch in the flange of the disk 27, as the latter revolves in the directionof the arrow, strikes the stop the latter will yield to a limited extent, and thus diminish the shock. A small pin, 41, projecting from the head 39 through a slot in the stop, maintains the latter in its properlateral position on the said head. A treadlelever, K2, pivoted to an attachment on the floor, is connected by a rod, 4-2, to an arm, 43, of the thrcearmed lever Ft, which is pivoted to abraclzet, .46, Fig. 12, on the frame of the machine. The arm ll5 ofthe lever is connected by the rod 47 to the elastic rod 38, a spring, 4S, tending to force the rod in the direction ot' the arrow. An arm, 49, on the verticalshaft 31, istconnected to a rod, 59. which is arranged to slide in suitable guides, 51, on the frame of the machine, and the arm 44 of the threearmed lever Itl is caused to bear on the top ol' this rod, near the end of the same, the rod being provided with an enlargement, 52. There is a hand-lever, 53, on the vertical shat'tl.

IIS

from the disk 27 and the shaft N Vhen the several parts above described are in the positions shown in Figs. 28, 29, and 3l.,

f/to be rotated.` At the same ti me i he shi fti ng-'oar is so operated as to move the drivi rig-belt from the loose pulley 3 tothe fast pulley 2, and the sliding bar 50 has been moved to a position where its enlargement is beneath the arm 44 of the th ree-armed lever R2, and this prevents the return of the stop 2S after the treadle has been released. rlhe counter shaft is now rotating, but at a less speed than the drivingshaft, as the effective diameter of the pulley N* is greater than that of the pulleyN, and itis important that the machine should operate slowly when first started, the speed heilig subsequently increased. In order to do this, the attendant seizes the hand-lever 23 and turns it with the shaft 2l, to which it is at tached, in the direction of the arrow unt-il it is arrested by the projection 26 on the edge of the fiange 25. By this movement the lever D? is so operated that the loose part 5 of the pulley N3 will be moved nearer t0 the fixed part, and the effective diameter of the pulley will be increased, that of the pulley N* being correspondingly decreased, and the speed of the machine being consequently increased.

It may be necessary from time to time while the machine is in operation to decrease the speed to some eXtent-as, for instance, when complex parts of' patterns are being embroidered. In order to do this, all that is necessary is for the attendant to turn the hand-lever back to an extent which the desired reduction in speed .may suggest.

In order to stop the machine, the first thing to be done 'is to turn back the hand-lever 23 until it can be again introduced into the notch 24 ofthe flange 25, as shown in Fig. 29, a movement which results in the'reduction of the speed of the machine, owing to the alteration of the pulleys N3 and N", due to this movement of the hand-lever 23, for it is as important for the speed to be lowered before stopping as it is to start the machine at a low speed. The hand-lever 23 being now in the notch of the flange, it is pushed forcibly back into the same and against the end ofthe guided rod 29, thereby turning the shaft 3l to such an extent that the shiftingbar will move the belt from the fast to the loose pulley. At the same time the three armed lever R2 will be relieved from `the control of the enlargement 52 on the rod 50, and the spring` 48 will then be at liberty to force the rod 47 in the direction of the arrow and the stop 28 to such a position that it will arrest the wheel 27, and consequently the shaft N, at the point desired.
